The formation of precipitates, which appeared in the body of the cation-exchange resin beds during the chemical separation of carrier-free samples from proton-irradiated cyclotron targets of more than 50 mg of rare-earth oxides, is investigated. The properties and character of this insoluble salt are discussed. A method for such a separation, which avoids the disturbing influence of a precipitate, is given. The sample produced is suitable for beta ray spectroscopy. The method described is applicable to fairly short-lived rare-earth isotopes, as the procedure can be carried out within 8 hours.
